Identify the incorrect relationship

Magnetic moment of an electron in hydrogen atom due to revolution around nucleus is $\frac{hS}{2\pi }.$ Here $h$ is Planck's constant and $S$ is specific charge of electron. Kinetic energy of this electron is

If ${\mathrm{He}}^{+}$ion undergoes transition $n=2\to 1$ the ratio of final to initial magnetic field due to motion of electron at the nucleus will

An electron in a hydrogen atom makes a transition such that its kinetic energy increases, then

A hydrogen atom in ground state absorbs $12.09 \mathrm{eV}$ of energy. The orbital angular momentum of the electron

An electron in a hydrogen atom makes a transition $n_1\to n_2$ where $n_1$ and $n_2$ are principal quantum numbers of the states. Assume the Bohr's model to be valid, the frequency of revolution in initial state is
eight times that of final state. The ratio $\frac{n_1}{n_2}$ is

An electron of mass $m_e$ is moving in $n^{\mathrm{th} }$ orbit of hydrogen atom. Magnetic field at centre due to motion of electron, is($r_0=$ Bohr radius)
